The travel season is fast approaching, and juggling tickets, hotel reservations, rental cars, itineraries, and other plans can be maddening. Which app or service do you use to keep it all organized so you get where you're going on time and safely? This week, we want to hear which travel planning services are the best.

Keep in mind here we're talking about travel planning tools, not travel booking tools, so the same site that can get you a deal on airfare or a hotel room may not be the best app to keep your plans organized in the right place or let you know if there are any problems or better bargains along the way. Have a preference? Let us know in the discussions below!

The call for contenders is closed! To see which of your nominations made the top five, head over to our Hive Five feature, the five best travel planning apps! Don't forget to vote for the all-out winner in our poll!
